Add QPdfSearchModel, QML PdfSearchModel and PdfPageView

This enables searching a PDF for a text string and getting the
boundaries of the areas where it is found.  The boundaries are returned
as polygons intended to be rendered with PathMultiline.

PdfPageView is a QML component intended to be a drop-in viewer for use
in applications that need the most common PDF viewing functionality.
More advanced applications are free to use it as a starting point for
customization.
